Advanced Code Snippets with Reference to Forum Posts

Please note that advanced manipulation of the cart or checkout via javascript is not supported by FoxyCart, and you can break things causing lost orders, errors, and global catastrophe. The links here are provided for reference, and they very likely will not work without tinkering requiring at least intermediate javascript knowledge.

Are you using FoxyCart version 2.0? Due to a complete revamp of the javascript in version 2.0, none of the below snippets will work in the new version. See this page for snippets for 2.0.

Shipping Snippets

Versions 0.7.1 and older: Note that applying javascript shipping modifications using either live or flat rates where you are setting custom values has been found to not work as expected for subscription based products where you need the shipping to apply to each subscription renewal. A fix is in place for versions 0.7.2 and newer.
